Description and Introduction

VR11.1, 4-Phase PWM Controller with Light Load Efficiency Enhancement and Load Current Monitoring The ISL6334IRZ is a dual-output PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** INTERSIL  
- **Type:** Dual-Output PWM Controller  
- **Input Voltage Range:** 4.5V to 24V  
- **Output Voltage Range:** Adjustable (0.6V to 5.5V)  
- **Switching Frequency:** 200kHz to 1MHz (adjustable)  
- **Number of Phases:** 1 or 2 phases per output  
- **Current Balancing:** Precision current sharing  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 40-Lead QFN (6x6mm)  

### **Descriptions:**
- The ISL6334IRZ is designed for high-efficiency voltage regulation in multi-phase DC-DC converter applications.  
- It supports two independent PWM outputs, each configurable for single or dual-phase operation.  
- The controller includes adaptive voltage positioning (AVP) for improved transient response.  
- It integrates MOSFET drivers and provides overcurrent, overvoltage, and undervoltage protection.  

### **Features:**
- **Dual Independent PWM Controllers:** Supports two separate voltage rails.  
- **Adjustable Switching Frequency:** 200kHz to 1MHz for flexibility in design.  
- **Precision Current Sharing:** Ensures balanced load distribution in multi-phase configurations.  
- **Adaptive Voltage Positioning (AVP):** Enhances transient performance.  
- **Integrated Drivers:** Reduces external component count.  
- **Protection Features:** Overcurrent (OCP), overvoltage (OVP), and undervoltage (UVP) protection.  
- **Programmable Soft-Start:** Prevents inrush current issues.  
- **QFN Package:** Compact 40-lead 6x6mm form factor.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
